The standard backup tool for PostgreSQL is pg_dump - this indeed just
backs up the data. You should not rely on copying the files of a running
database - that won't always work.

Ah - I think I see what you're trying to do. It's quite common to have
e.g. Apache+PHP/JBoss/etc on one machine and PostgreSQL on another. All
that's required is to turn the tcp connection option on in PostgreSQL
and change the connect string in the application.
Don't forget to update your pg_hba.conf to allow your application to
connect from the remote machine too.
